The CLEAR Act amends federal transmission facility permitting rules to streamline the approval process for new electric transmission projects. The bill designates the Federal Energy Regulatory Commission as the lead agency overseeing coordinated federal authorizations for transmission facilities and requires all federal agencies involved in the permitting process to publish their final decisions in the Federal Register. The legislation also mandates that the Department of Energy consolidate all review and permit records for a single transmission project into one joint record of decision whenever practicable. Additionally, the bill establishes that all federal authorization approvals are treated as orders from the Commission, allowing challenges to be raised through a single rehearing and judicial review process rather than through multiple separate legal proceedings. This change affects electric utilities, transmission companies, and other stakeholders seeking to build new transmission infrastructure, as well as parties who may wish to challenge these projects in court.
